Laser-Driven Proton Therapy: Strong Physics, Hard Road to the Clinic
A follow-up to my post on VHEE electrons: why laser-driven proton acceleration is great physics but, in my view, unlikely to become a competitive medical product — and where its real strengths are.

WIMP detection reaches critical threshold
Four decades of WIMP searches reach 2.2×10^-48 cm² sensitivity—just one order of magnitude from the neutrino floor that will either reveal dark matter or redirect physics toward axions.

The quiet decline of recombination X-ray lasers
While X-ray laser research thrives globally, plasma-based recombination schemes that showed promise in the 1990s have quietly faded from mainstream science.
